Abstract (en)

[origin: EP0323066A2] A system for determining the road adhesion of a tire installed on a road wheel of an automotive vehicle operating on a roadway includes a road wheel turn angle measuring means (24), a vehicle speed measuring means (22) and a steering force measuring means (26). Information regarding turn angle, vehicle speed and steering force are fed into a processor (16) which determines the road adhesion of the tire.
